CHEMICAL FIRE-ENGINE.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed April 14. 1906- Serial 110.311.690-

To all whom it may concern:

Be it known that we, THEODORE Lnnon and HAROLD S. CLARK, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Chemical FireEngines, and we do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to chemical fire engines, and theinvention consists in the construction and combination of parts substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings Figure 1 is an elevation of the mixing tank or receptacle of the engine partly in section at the top and showing the bottle suspended therein, and Fig. 2 is an elevation of the bottle and its supports partly in section, as hereinafter fully described.

The invention as thus shown is found, first, in the means for carrying the main tank A, in which the chemicals are mixed as usual and which has the requisite opening for the emission of gas, not shown.

B is the supporting band for the tank which is shrunk fixedly thereto, and b are trunnions secured to said band above the middle so as to throw the greater weight below the band and counterbalance the tank.

Another important feature of the invention is found in the means for closing and opening andfor supporting and tilting the lead bottle G contained in the outer receptacle or tank A. These means comprise several different elements, consisting of the cover or cap H, constructed to seat in and upon the neck of the bottle substantially as shown and constituting a perfect stopper and seal therefor when down as in Fig. 2. Said cover H has a threaded stem h projecting centrally through the top or head a on or for the outer of main tank, and said stem is provided with a crank wheel or handle it to run the cap H quickly up on said stem off of neck g of inner bottle G when the engine is to be used and the chemicals mixed. But a further operation occurs as the cap H is thus run up, which takes place in and through the arm 2 which is rotatably held on the neck of cap H at one end and extends downwardly to about the middle of bottle G at one side thereof at its other end and at right angles to the hangers J on which bottle G is at its bottom. Thus, the said bottle is its bottom resting on and soldered to a band or ring L, and the hangers J pivotally engage this ring at g off or at one side of the vertical center thereof, Fig. 2. Said hangers are rigid in or with tank top a, being threaded into the same in this instance, and

between the same to discharge the contents, dotted lines Fig. 2. Arm 2 has an oblong slot 4 in its lower end adapted to engage a lug 5 on stem 6 rigid with ring L, and said stem or standard 6 and arm 2 are on the short side of pivots or lugs g, so that when cap H is raised and bottle G would ordinarly tilt by gravity to position dotted lines Fig. 2, the said bottle will be positively engaged by arm 2 and thrown to discharging position. This construction and arrangement of parts also makes everything within and upon the main tank removable together, including top a which covers or incloses said tank, thus working a great convenience for substituting a filled bottle.

To prevent creeping of gas out about threaded stem 7 we provide a seat a on the under side of cap a adapted to engage a gasket or packing 72/ about said stem and this may be further supplemented by packing about the base of said stem.

Another feature of convenience is the construction of hangers J which have open hooks 12 in which lugs or projections g on ring L engage. The hangers J are rigid, and the hooks 12 are of substantially goose neck pattern with the point 13 of the hook extending back into the neck thereof across the engaging point so that the bottle will be securely confined in said hooks for service while at the same time it can be easily removed and replaced.

What we claim is 1. In-a chemical engine, a main tank and a support on which the tank is adapted to be tilted, a removable cover for said tank and hangers on the inside thereof, in combination with a bottle supported-on said hangers in a tilting position, and means to tilt said bottle comprising a screw on aged through said cover, a stopper for the ottle on said screw and an arm connected with said screw at one end and adapted to engage a stem on the bottle support at its other end.

2. The main tank and the cover therefor supported 7 shown as having an annular shoulder 3 near bottle G is adapted to rest and to be tilted and rigid han ers from said cover having hooks at their ower ends bent inward over the engaging portion thereof, in combination with a bottle and a support therefor having legs engaged in said hooks, an upright stem on said support, an arm engaging said stem and a screw through said cover on which said arm is supported, whereby when the said screw is run up the said arm is raised and the bottle is tilted.

3. The main tank and the removable cover thereon, and a pair of hangers removably engaged in said cover, in combination with a bottle supported about its lower portion upon said hangers in a tilting position, a
